Abstract: A tunable hyperspectral-polarimetric filter system includes a first polarizer, a crystal filter and a second polarizer. The first polarizer is configured to transmit light in a first direction of linear polarization. The polarization selection may be substantially the same for all wavelengths at a spectral range of interest. The crystal filter, may be parallelly and coaxially disposed after the first polarizer. The crystal filter is configured to rotates the first direction of linear polarization for light transmitted by the first polarizer, wherein rotation angles differ for different wavelengths at the spectral range of interest. The second polarizer may be parallelly and coaxially disposed after the crystal filter. The second polarizer may substantially transmit a second direction of linear polarization of the light transmitted by the crystal filter. The first polarizer and/or the second polarizer are rotatable to tune for different transmission spectra for spectral and polarimetric imaging resolution.
